To all whom it may concern: Be it knownthat we, HARRY H. Konnn MAN and Ronnn'r G. LEIMBERGER, citizens of the United States, residing at Newport, in the county of Campbell and State of Kentucky, and at Cincinnati, in the county of Hamilton and State of Ohio, respectively, have invented a new and useful Improvement in Attachmentsfor Manifolding Typewriters, of which the following is a specification; Heretofore manifolding typewriters of the general type which we have disclosed herein, have necessitated the employment of especially printed and folded paper. Such an arrangement necessitating the use of this especially printed and folded paper, commonly known as fan fold, has several objections. Among these objections may be mentioned the necessity under such an arrangement, of having all the sheets of one color, weight and quality of paper because of all copies having to be printed simultaneously upon a single web of paper pass ng through the press. Another ob ection is that the printing has to be done upon one side of one copy and upon the opposite side of the adjacent copy in order to have all the copies right side up when fan-folded ready for use ill tilt typewriter. Aside from the special presses needed to print, perforate and told flan-fold paper supply, no very convenient l'l'liUHHl oi storing it when in use in the typewriter. has been developed, boxes or baskets being used usually to hold it.

ln the invention now to be described, an object ha's 'bcen to produce a device for securing several copies of a written record upon a series of separate superimposed sheets of paper, in a manner such that each copy may be upon a sheet of different color or quality of paper.

A. further object is to produce a device for securing several copies of a typewritten record upon separate sheets which are mane tained in perfect registration with one another so that the typewritten matter will appear in the same relative positions on the several sheets.

A further object is to produce a device in which the manner of storing or holding the supply paper is not only compact, but

also contributes to the ease withwhich the sheets are handled and the speed with which the records may be produced.

A further object is to produce a device of the character described, for which the paper supply may be produced relatively cheaply and without having to resort to machinery of special construction for its production.

A further object is to provide an improved means for mounting paper rolls in a manner such that the ends of the rolls will be maintained in perfect condition by being prevented from becoming mashed in or otherwise damaged.

These and other objects are attained in the device described in the following specification and illustrated in the accompanying drawing in which:

. Fig. 1 is a perspective view of a manifolding typewriter having a device embodying .our invention attached thereto.

Fig. 2 is an enlarged composite View of a paper roll and a roll mounting means embodying a detail of our invention.

Fig. 3 is a fragmental perspective view upon an enlarged scale of a detail of the roll mounting means embodying a detail of our invention.

Fig. t is a fraginental perspective view upon, an enlarged scale of a modified form of mounting means for the device which we will now describe.

In the drawing we have shown in Fig. 1 a nanifolding typewriter 5 of conventional form, and having a rearward frame extension (5, mounted upon a table 7 designed to support it. The usual transversely reciprocable carriage 8 is mounted on the main portion of the frame for reciprocation largely upon track 9, while a. rearwardly extending portion 10 of the carriage travels upon a track 11 which is supported by frame extension 6. Upon extension 10 a secondary carriage 12 is mounted for movement "forwardly and backwardly of the carriage extension 10. This carriage 12 carries the bars 13 which extend between the sheets and which carry the interleaved sheets of carbon paper by means of which the several copies are made. A forwardly extending handle 14 ermits this carriage to be operated as will be described later.

Upon carriage 8 a rearwardly inclined arm 15 which carries two aligning pins 16, permits of the proper alignment of the sheets as will also be described later. Two outwardly bowed elements 17 and 18 which may be detachably connected with frame extension 6 by means of thumb nuts and bolts 19, or directly to table 7 as shown in Fig. 4, if preferred, are provided for sup porting the main portion of the device. To the upwardly and inwardly extending ends of the members 17 and 18 we secure vertically disposed supports 20 and 21. Support 20 is provided with a series of forwardly and rearwardly extending arms 22 and.23 which support the paper rolls 24: and guide rollers 25 respectively at one end. The opposite ends of rollers 25 are simllarly mounted, but the opposite ends of paper rolls 2a are mounted as we have shown in detail in Figs. 2 and 3. In this mounting both ends of each paper roll are provided with pressed sheet metal cups or thimbles 26 which, having flanged edges, are pressed into the open ends of the hollow centers of each roll. Lugs are provided on the roll carrying ends of arms 22 for engagement with the interiors of thinibles 26 in the same manner that lugs 27 are provided on theroll carrying ends of a series of movable arms 28 which extend from support 21 and which are mounted movably on the support for permitting of the removal and insertion of rolls of paper. This movable mounting is accomplished by providing two pins 29 and 30 which extend from support 21 for each arm to be supported and upon which the arm is loosely mounted. Between these pins a headed pin 31 is mounted on support 21, the arms also being loosely mounted on this. A spring 32, preferably of spiral, conical form, is located between the head of pin 31 and the face of the arm 2850 that the arm is held yieldingly against support 21.. lhis permits of the ready removal and placing in position of rollsof paper. In the event of double arms, as shown in Fig. 3, the sup-ported ends are merely overlapped as shown, it being'as easy under these conditions to move one as readily as the other. Beneath the roll supporting arms we have located a sheet supporting plate 33 which has downwardly ex tending lugs 34.- 'lhese lugs are secured to supports 20 and 21 by means 'ofthumb bolts 35 so that the plate may be adjusted for inclination, as shown. Extending rearwardly' from members 17 and 18 is a paper supporting loop 36 which is dropped to provide side guides 37, the loop su porting the rearward portion of loop 38 o .the as .sembled sheets of' paper, bar 39 of the carriage extension 10 supporting the forward portion of the paper loop.

In the operation of our improved device -not new, having been known for some time it is but necessary to place in the roll-holding rack the required number of paper rolls of the desired colors, qualities and weights. This operation is accomplished by placing one end thimble 26 of each roll over the lug of arm 22 which is to support that end of the roll. The opposite end of the roll is then supported by pulling outwardly upon its supporting arm 28 in order toallow the opposite thimble 26 of the paper roll to be brought into registration with the supporting lug 27 carried by the arm 28. By then releasing its arm 28, the lug 27 carried thereby is brought into supporting engagement with the thimble of the roll. The several rolls having thus been mounted in the rack, the paper sheets are brought in proper sequence over the rollers 25, over plate 33 and over loop 36 as shown. The sheets are then brought one at a time over bar 39 of carriage extension 10 and are interleaved with the carbon sheets carried by bars 13 of carriage 12. The assembled sheets of paper and carbon are then passed over the platen roll 40 of the typewriter and the apertures 41 of the paper are plawd-over the pins 16 of arm 15 in order accurately to align the sheets and the printed forms thereon. lhe sheets having thus been aligned, and. the carbon sheet carriage 12 having been moved to the rear of carriage extension 10 by means of arm 1 1,150 withdraw the carbon sheets from. the first aligned forms of the paper record sheets, these are torn ofi. By then operating the typewriter in the usual manner the printed forms are filled in with the record matter desired. The forms having then been filled in, they are aligned as previously described, are freed from their interleaved carbon sheets, and are torn oif ready for distribution to the various departments of the factoryor to be used as otherwisedesircd. v'llhe typewriter is then once more in condition for use.

It will be understood that that portion of the typewriter which embodies the main frame 5, the frame extension 6, carriage 8, carriage extension 10, and carriage 12, are

and having been used in the fan-fold method of manifoldin to which we have previously referred. l or this reason we have not been specific in the description of any portion of the typewriter or its use. However there are features of our inven-' tion to which we direct particular attention. We direct attention first to the features which permit of the formation and maintenance of paper loop 38. By reason of this loop the carriage is permitted tohave unimpeded transverse reciprocation without tearing or buckling the paper. ,A feature which aids in the-maintenance of the loop is the inclined plate 33. By pull- 13 naeaeso ing forwardly 7 upon the assembled sheets in the vicinity of roller 25, enough slack is created topermit the Weight of loop 38 to aid in drawing the sheets over inclined plate 33 which may be given the necessary inclination to facilitate movement of the paper downwardly. -The outwardly bowed members 17 and 18 permit transverse reciprocation of the typewriter carriage and the sheets it carries, but the downwardly extending sides 37 of loop 36 prevent displacement of the sheets should there be a tendency toward sidewise movement thereof. According to the smoothness, weight and numbers of sheets of paper coming from the rack, the inclination of the plate 33 may have to be varied in order that the gravitational pull of loop 38 may be assisted to maintain the'length of the loop. Another feature to which we call attention is the advantage attained in the manner We have chosen to mount the paper comes from the factory, it

supply rolls. We refer particularly to the thimble 26. This element serves to support the paper at the ends of the roll, preventing it from being crushed in, as well as furnishing a bearing bushing upon wluch the roll may revolve. It is also better than a spindle because-there is no wear and the consequent wastage of paper resulting therefrom is saved. In the use of, the thimble each roll is thus rovided as it,

eing unnecessary to supply fresh thimbles for each roll as it is used.

At times it may be desirable to use two or more different sets of paper rolls in the course of using the typewriter; that is, 1t may he necessary to use a set of rolls having a difierent setof forms or to use a set in which the formsare printed upon a different colored paper. In such an event we contemplate the detachable mounting of the rack supports and 21 upon the members 17, and 18, utilizing the bolts 35 for this purpose as well as for the adjustment of plate 33, Thus by roviding two or more racks 'in which the different sets of rolls are mounted, the change from one to the other may be madequickly and without having to change the rolls in the rack each time it is required.

Having thus described our invention what we claim is:

1. An attachment for manifolding typewriters, comprising in combination with a typewriter, a roll-carrying rack above the typewriter, a series of paper rolls mounted in the rack, a rearwardly extending paper supporting ,loophaving guiding sides, and

an adjustable plate between the rolls and the loop adapted to direct the paper from the rolls over the loop,- whereby a loop of paper may be established and maintained between the typewriter and the loop.

2. An attachment for manifolding typewriters, comprising in combination with a typewriter, a roll carrging rack secured to the typewriter and a aptedto support a paper supply roll above and in spaced rela- .tion to the typewriter, a plate located between the typewriter and roll located in the rack, adapted to receive and sup ort the paperpassing from the roll, an means adapted adjustably to hold the plate on the rack at such an angle that maintenance of a loop of paper will be aided by the weight thereof acting to draw the paper from the roll.
